Figure B.9 SeaHawk LD5100/LD2000 Distance Read Leak Detection (Dry Contact)

The F3400/F1000 averages/filters the analog inputs. The LD5100 will output approx. 3.95mA 

when there is no leak. The LD5000 will output a value between 4mA and 20mA when there is a 

water leak. The low limit 1 and low limit 2 set points should be set to a 0 value. High limit 1 

should be set to a value, in feet, that represents 4.0mA (1 foot). This allows the F3400/F1000 to 

alarm whenever there is a leak. The high limit 2 should be set to a value, in feet, that will control 

the internal relay, if needed for the application. The Cable Fault relay, from the LD5100 should 

be tied back into the F3400/F1000 to detect a fault with the 5100 controller/cable. The analog 

output is only used for a Leak alarm distance.
